D Dolity Mini-rambo 1.3 Mainboard For 3D Printer

Brand	Unbranded
Manufacturer	Unbranded

This is a motherboard for a 3D printer. It is based off of RAMBo, the Arduino MEGA design, and the work of the RepRap community. It has 4 stepper drivers and 4 mosfet switched outputs. It is Arduino MEGA compatible and has Atmega2560 and Atmega32u2 processors. It also has 3 Thermistor jacks,Motor Drivers,4 A4982 1/16th microstep motor drivers,PWM Outputs for (XY), Z, E0 stepper current control instead of digital trimpot,Current limit on driver IC VCC to prevent permanent latchup,Microstep mode configured by MCU through firmware (no jumpers needed), and Test points for driver control signals.
